SUMMARY OF INVENTION It is a feature of the present invention to provide a magnetic game which may be played by people of all ages as it does not require any special skills for execution.

It is a further feature of the present invention to provide a game which is economical to produce and safe to use.

According to the above features from a broad aspect, the present invention provides a magnetic game comprising a board of non-magnetic material having a flat upper surface. A plurality of spaced apart pins of ferrous material are secured to the board and protrude above the upper surface thereof. A first and second magnetic disc of like polar disposition are provided whereby the discs repel each other when in close proximity to each other. A pusher means is provided for re straining and moving one of the discs on the board upper surface whereby to cause the other disc to be repelled and displaced on the flat surface.

BRIEF DESCRIPTION OF DRAWINGS A preferred embodiment of the present invention will now be described with reference to the accompanying drawings in which:

FIG. 1 is a plan view of the game board of the present invention.

FIG. 2 is a sectional view taken transversely of the game board; and

FIG. 3 is a plan view of the pusher means and the discs.

DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to the drawings and more particularly to FIG. 1, there is shown generally at the magnetic game of the present invention. The game comprises a board 11 constructed of a non-magnetic material such as wood, plastic, etc. Hereinshown, the board is of rectangular configuration and is provided with a flat upper surface 12. The upper surface defines a playing surface area 13 and a starting area 14 where a pusher means 15 and two or more magnetic discs 16 can be stored when the game is not in use. The playing area is also subdivided into zones which are defined by spaced apart transverse lines 17, each zone having a particular designated value.

A plurality of spaced apart pins 18, of ferrous materials are secured to the board and protrude above the upper surface 12 of the board, as is clearly shown in FIG. 2. As can also be seen from this figure, the board is provided with vertical sidewalls 19 which extend above the flat upper surface 12. Side rails 21 of ferrous material are also provided on the inner surface of the sidewalls 19. The rails 21 and pins 18 provide magnetic attraction to the discs when the discs are in close proximity thereof.

At least two magnetic discs 16 are provided and have at least a known polar disposition each of which are identified by suitable means such as paint on a surface or markings (not shown). Both discs are placed on the upper surface of the board with both their north or south pole facing upwardly or downwardly whereby they will repel each other when brought in close proximity to each other. The pusher means 15 is an elongated flat member constructed of non-ferrous material, i.e., wood, plastic or non-ferrous metals. The pusher is provided with a disc engaging end 25 in the form of an arcuate slot and having a curvature corresponding to a portion of the periphery of the discs 16. The arcuate slot 25 is provided to receive a portion of a disc 16 positioned on the flat upper surface 12 of the board whereby the pusher means can displace the engaged disc on that surface whilst restraining it from lateral displacement due to magnetic attraction by the pins 18 or the side rails 21.

Referring again to FIG; 1, it can be seen that the pins 18 are equidistantly spaced from one another. The spacing between the pins is at least twice as great as the diameter of the discs (see FIG. 2). Also, the pins 18 are disposed on circumferential parameters 26 which extend concentrically about a central pin 18' secured at the center of the playing surface 13. The magnetic power of attraction of the pins and rails will depend on the iron content in these metals and is considered when determining the spacing of these relative to the size of the discs.

The zones which are delineated by the lines 17 are given values as stated hereinabove. Also, in the upper zone there are provided target markings 27 which have a higher value than the zones, for reasons which will be described later.

The operation of this game is as follows. The object of the game is to displace one of the discs 16 through the playing area 13 starting from startline 28 and moving towards the other end of the playing area, that is to say, through the zones of increasing values. The discs are displaced as follows. One of the discs is engaged in the arcuate slot 25 of the pusher l5 and is brought in close proximity to the other disc or free disc. As the disc engaged by the pusher is brought closer to the other one, it will repel the other disc as described above. Thus, the free disc must be guided between the pins and substantially along a path which extends mid way between adjacent pins. This path is the one of least magnetic attraction as it is the furthest path from adjacent pins. If the free disc is guided closer to the pin it will be attracted to the pin and come in contact therewith. When either discs are attracted to a pin, then that player has terminated his turn at the game and will score according to the designated value of the particular zone where the disc has stopped. The targets in the upper zone are of higher value as they are more difficult to attain seeing that they are located in an area where the free disc must be guided through a great number if pins before arriving there. As mentioned hereinabove the side rails also attract the discs and the player must guide the free disc away from the side rails.

It is within the scope of the present invention to provide a board of different configuration to that as defined herein. For instance, the board could be circular with the starting point at the center of the board and the discs moved away from the center towards the periphery. On the other hand, the disc could be moved from the outer periphery to the center of the board. Also, many players could play at the same time. Still further the sides and configuration of the pins and discs 16 may be altered depending on the magnetic power of attraction required between them. Still further the pusher means can be modified to positively engage one of the magnetic discs 16. For example, one of the discs could be provided with a cavity on a surface thereof, and by inserting a pin in this cavity one of the discs can be controlled whereby to guide the free discs through the pins. Still further the pusher means may be angulated in the disc engaging end area thereof whereby the hand can be held above the upper surface of the game board whilst the disc engaging end area is substantially flat on the upper surface of the board.
